These beetles inhabit lawns and meadows, especially with yellow flowers of Apiaceae species. Cryptocephalus sericeus can reach a length of about 6–7 millimetres (0.24–0.28 in).

Rare
Under 5% of wildlife watchers report a Cryptocephalus sericeus sighting in Prague on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 288th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Cryptocephalus sericeus in Prague on a given day, against under 5% in September to May, the lowest months. Those are among Prague's wettest months, with about 80 mm of rain a month against 30 mm in February.
Only Prague, in our data
Prague is the only city on Wallace's Line with enough records to rate Cryptocephalus sericeus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cryptocephalus sericeus is recorded against all the insects logged in Prague (18 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
